Description
Technical field
The utility model relates to artificial swamp fields, more particularly to a kind of tableland formula artificial wet land treating system, especially
Suitable for the environment in river or lake side slope with certain drop, and it is suitable for urban landscape water system purification of water quality.
Background technique
Urban landscape water system is component part important in human settlement environment in city, is the outdoor surface water newly excavated mostly
System, the ecosystem is very fragile, and self-purification capacity is poor, easily becomes the receptor of resident living sewage, rainwater and rubbish, causes not
With the pollution of degree, water body blackening is fouled or even eutrophication, some water bodys even become stagnum, smelly pond, seriously affect
The natural environment of surrounding and the living environment of resident.Therefore, the water environment treatment of urban landscape water system is very urgent.
The low cost control of efficient quick improvement and micro- pollution phase when the control of urban landscape water system quality includes heavily contaminated
Technology, current Treatment process can be divided mainly into physics, chemistry and biological three classes method.Physical method be primarily referred to as dredging bed mud,
Mechanical algae removement, diversion erosion and deposition etc., chemical method include that chemical agent is added to kill algae, the precipitating that molysite promotion phosphorus is added, stone is added
Grey denitrogenation etc., such methods are quick, but at high cost, easily cause secondary pollution, are commonly used in emergency response measure, these technologies
Purify landscape water body to a certain extent, but method is limited to.Currently, people gradually recognize ecological management it is stable,
The advantages that long-acting, slowly turns to ecological remediation and treatment landscape water body river.Ecology-bioanalysis is guidance, people with ecological principle
Work culture anti-pollution and aquatic animal, plants with purification function are restored in landscape water body using interbiotic interaction
Or the ecosystem of balance is established, enhance self detergent power of water body, to make water body be purified, its advantage is that processing effect
Fruit is good, low cost, energy consumption is low, operating cost is low etc., often uses such method at present.Ecology-biological method generally includes to give birth to
The technological means such as object chinampa, bio operon further include a series of restorations of the ecosystem such as artificial swamp, stabilization pond, biological grid and are protected
Nurse's journey.
